My b2evolution Version: 1.10.2

One of the advertised features is the ability to have separate domains from just one install base. I'm trying to accomplish this with my two sites, and here's the set up:

DomainA (b2evo installed here}

DomainB

Both domains under one hosting account.

Installation couldn't be easier, and blogA (DomainA) is up and running

Now to domainB!
In the admin side under the Blog Settings tab, I chose Absolute url for the Blog Folder url, and have tried all the different options under Preferred access type. Also, in the Url Preview, it gives the correct url as: domainB.com.

The problem is I can only access domainB relative to DomainA, i.e., domainA/index.php?blog=2, or domainA/b_stub.php.

Question:

Is there something I need to install under the domainB directory or are there additional config steps that I'm missing?

TIA
